Thanks in advance for any and all help! I’ve been creeping on here for a while, and finally bought a used Honda. It runs fine usually, but now I’m having some issues....

I have a 2012 Foreman 500FPE. The shifting is intermittent. Codes 22 and 23 are showing up. I have tested the angle sensor and it appears to be within specs. I have reset the codes when the shift buttons are responsive, and I get the same codes.

Sometime I walk up to the machine, and it shifts fine. Other times I get no response from the shift buttons upon startup, but it is responsive when the key is on with the engine not running. Other times the buttons are not responsive with the engine off and key on. If I pull the curse in the back, it shifts for a moment, then flashes.


So far I have:
1. Checked fuses-all are good. Also, when I get no response from the shifting buttons, pulling fuses resets something, and allows me to shift for a moment. Then it freezes again.
2. Checked the wiring connection from the harness the shift motor. It is clean with no corrosion.
3. Verified that the battery is at full charge.

Not really sure where to go from here, just hoping someone has some insight!

fish, ya trying to break the newbie,s in right. :devil
ya forgot,, a case of bud, an a manual. the case of bud is so ya read the pages correctly.

Clean thoroughly and dielectric grease every harness connector pair on the bike and you'll probably fix it. Clean and grease the shift switches too. Don't forget to polish and grease the motor and frame grounds... welcome to the forums!

I was given a manual with the machine, but it hasn’t arrived yet. It’s also for a 2006 model not a 2012. I have been told the transmission/shifting section is nearly identical for each respective manual.

Hopefully the 30 rack of Busch Light in the fridge will be interchangeable with the Bud Light.

I’m going to pick up some grease this weekend. Sounds like a tedious task, but I’m sure it’s for the better regardless. When you say shift switches, are you referring to the module on the handlebars with the up/down arrows?

Yeah, the shift switches are not sealed, so they can get water inside them each time you wash the bike or it is left outdoors in the rain. I always take them apart and clean them, then pack them with dielectric grease. I still screw up and carelessly hit 'em with the pressure washer spray once in a while though. Be careful prying on the plastic rocker switch retainers if you take yours apart, they look pretty fragile.

BTW, I think there is a service manual for your bike linked from the manuals thread.

https://www.hondaatvforums.net/foru...nual-help/50817-service-manual-downloads.html

If I'm not mistaken there is one that covers from about '05 up through '14, for all Foreman models.

None of the harness connectors are waterproof from the factory although they are supposed to be... generally a good dielectric greasing of each connector pair solves electrical/sensor/shift problems and prevents them from reoccurring. One pressure wash is all it takes to get water in them if left untreated.

Keep us updated if you can...

the manual i was talking of was the service manual, ^^^^ above, or a clymers manual. :smile

Ok, so my manual came today. It’s a 2009 but I’m told for the shifting issues it will work. I also got the dielectric grease. I plan on greasing all connections this weekend, as well as taking the switch apart and lubing it up.
I also noticed today that the machine jerks forward pretty significantly from neutral to forward. Much more than any manual I’ve ever driven. Because the machine is EFI, I don’t believe I can turn down the idle. So I am assume I need to adjust the clutch, which from other threads seems easy enough. Is lurching forward a foot or so typical?

It sounds like it might need a clutch readjustment. When the clutch is not right it will struggle to shift cause the shift motor has to overcome an engaged centrifugal clutch. The motor must be warmed up too... else the electronically controlled cold enrichment idle speed will be high.
